I bought this, I'm trying to use it with my 50mm or 85mm, but I can't get it to focus, tried it in Manual focus, still wont work.

The tube makes your depth of field incredibly pronounce. You might want to remove all but the smallest ring. The actual focal length of your lens is fairly close to the actually lens. If you hold an object very close to the lens, you will be able to get the object in focus. For instance, lie the camera down in some grass. It makes the DOF so shallow, that only one or two blades will remain in focus.

The tube will not focus automatically. Since it is set up for fine photography, I use a tripod to keep it steady. A minor motion is all you need to focus. Remember if the surface is not even valleys will be in focus while higher points will not.

May I suggest you watch some videos posted on you tube for a clear explination as to how to correctly use these.

I had the same issue with the 50mm, until I realized that at a certain point you have to physically move in and out to achieve the focus you are looking for.

Hi personally it did not work for me. The camera becomes set back so far as a result of the mounting that focussing is a problem. For me other than macro work it was not suitable and certainly not as all round useful as I understood it to be. I returned mine for a refund

Yes Dorothy, you can use it WITH an adapter.I did this with and Em-5, and it will focus slowly, same as an EM-5 does with these lenses.The EM-1 will focus it about as fast as it can.Cheers from OZ!

I'm having the same problem using this lens on my D80 camera. What you are saying is that there is no way for me to use the ring to adjust the aperture? It only works when locked on 22?? This doesn't seem right.

I've totally forgotten since I sold mine with my long lens. Sorry. I can say that it worked well with both my 300mm 500mm.

Sorry...at the end, I was not able to use it. Did not work for my intentions. Did not have the right lens

It will only work in manual focus mode with the 50-500mm (i.e. you'll have to focus the lens manually). Like any other 2x converter it will not only double the focal length, but also decrease the aperture by two stop making the lens too dark for any camera to focus automatically (i.e. f/6.3 -> f/18 @ 500mm)!The camera autofocus only works on lens faster than f/2.8, like the 70-200 f/2.8 (or 120-300 f/2.8) for example with this 2x teleconverter

Dr. Smith thank you for the response, yes that helped, but I do have it set on 'M' and it still does the error 'FEE' so I am out of options. I cleaned all the sensors and made sure to listen to the 'click' when lens locks. I'm really unsure what is the problem now. Does this mean that I can only use the f/22 with this lens? Thank you so much! I appreciate your help.

be sure the two lenses are listed as compatible on the mfg web sites. Not all areotherwise the 2x works great.Take extra care with movement, use a tripodNot all lenses support auto focus with the 2x, try manual focus

I use a 70-300 Sigma. It will work but on manual you can zoom all the way and focus yourself. If your on auto focus it will work only till about 200 mm then it won't focus anymore. But this is what happens with this lens. Can say for sure if it will on any other. As for picture quality I did notice a fair difference. Not very clear when zoomed all the way. But need to try with a tripod. I got it for my birding and does not work well for that for me.

It just so happens that yesterday I tried the 2.0 on my 7D Mark II with the new 100-400 II lens and it lost its AF function. It works fine with the 1.4 extender, though.

John is correct. Check the front of your lens, if it says 52mm then it should work. Make sure that you are attaching the ring correctly. A reminder, you will not have focus ability via the lens. You will have to physically move the camera towards or away from an object in order to 'focus' the subject. Works great on my T4i until I can afford a proper macro lens.

I would love to help, but I can't find this lens to verify how it works. I do remember it worked on mine...

First extend it to full length, then adjust the focus. And you can only use it for distant objects. I don't have it now but I remember it do require some trial and error.
